https://devzone.nordicsemi.com/f/nordic-q-a/3054/hide-device-to-unknown-centralsHi, I&#39;m developing a HID-device using nrf51822, s110 ver 6.0.0 and SDK ver 5.2. I would like to hide the device from unknown centrals once it&#39;s paired. I&#39;m advertising using a whitelist with only one entry and setting filter policy to BLE_GAP_ADV_FP_FILTER_BOTHen-USTelligent Community 13Thu, 10 Jul 2014 12:49:21 GMThttps://devzone.nordicsemi.com/thread/11431?ContentTypeID=1Thu, 10 Jul 2014 12:49:21 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8d45709b-256d-410e-ab58-3cd39373d74bJonatan Blomster<p>I&#39;m not sure that we want to change the softdevice version now since this is a bit late in the development, but I&#39;ll have a look at it.

If you update, your device can use resolvable private addresses for advertising with less hassle. Other devices will then see that a device is advertising nearby, but as its address will constantly change between seemingly random numbers, they will not be able to track it. If you in addition have no advertisement data that can identify your device and use whitelisting to only let the known peer connect, your device should be as hidden as possible.</p> <p>BR, Øyvind</p><div style="clear:both;"></div>
